Abstract: 821,069. Gas-blast switches; pneumatic actuation of switches. BRITISH THOMSONHOUSTON CO. Ltd. Jan. 17, 1958 [Oct. 25, 1956], No. 32581/56. Class 38 (5). In a gas-blast circuit-breaker in which a moving contact 9 is separated from a co-operating contact 17 by a gas pressure applied to the arc chamber 1, the contact 17 is arranged to follow the contact 9 during the initial part of the latter's opening movement and is then arrested so that the contacts separate. In the form shown, the contact 9 is mounted on a rod 8 attached to shouldered piston 7 slidable within stepped cylinders 5, 6. The piston is urged to the left by a spring 11. The nozzle contact 17 is formed at the end of a tube 18 having parts 21 and 22 slidable within stepped cylinders 19, 20. The tube 18 is also urged to the left by a spring 23. Pressure gas applied to the arc chamber 1 from an inlet passage 4 passes through ports 25 and acts on the part 22 to move the tube 18 and also the contact 9 and its attached piston to the right. This movement uncovers ports 16 in the cylinder 6 so that the pressure gas is applied to the piston 7 moving it to the right. The following movement of the tube 18 is then arrested by the part 22 abutting the step 19a between the cylinders 19, 20 and the contacts separate, the gas blast passing down the tube 18 and through the ports 32a to the exhaust passage 31. Finally, gas leaks around the piston 22 and the tube 18 is returned to its original position by the spring 23, thus closing the exhaust passage 31. The contacts are therefore kept open by the gas pressure in the arc chamber 1. Release of this pressure allows the contacts to return to their original closed position.

Abstract: 1523604 Photo-electric measurement of roughners SVENSKA TRAFORSKNINGSINSTITUTET 5 Aug 1975 [5 Aug 1974] 32712/75 Heading G1A The roughness of a surface is measured by illuminating it with a parallel light beam at a given angle of incidence and determining (a) the amount of light reflected at an angle equal to the angle of incidence, or (b) the amount of light which is polarized perpendicular to the plane of incidence and which is reflected at an angle equal to the angle of incidence, and (c) the amount of reflected light which is polarized parallel to the plane of incidence; the roughness is found from the ratio of (a) or (b) to (c). In Fig 1 the surface 1 of a sheet of paper to be investigated is illuminated with a laser beam, which may be polarized. Light reflected at the angle of incidence, which is preferably within 10 degrees of Brewsters angle, passes to photodiode 4 via a polarizer 3. This polarizer is moved to and fro so as to select alternately the polarized light (c) above, and either all light or light polarized normal to the incidence plane depending on whether circuit 6 is to form the ratio with signal (a) or with (b). A polarizing beam-splitter may be used with two photodiodes to produce signals (b) and (c), Fig. 2 (not shown), or two photodiodes and polarizers may be used to produce these signals, with (c) being measured at an angle other than the angle of incidence, Fig. 3 (not shown).

Abstract: 894,717. Moderator structures. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 21 , 1958 [Oct. 21, 1957], No. 32860/57. Drawings to Specification. Class 39(4) The graphite moderator of a gas-cooled nuclear reactor is formed of blocks shaped and fitted ttogether so that anistropic growth due to irradiation causes curving of the fuel rod channels without disturbing their continuity, thereby preventing cooling gas leakage. The blocks are spigotted together at their upper and lower faces, the spigots being curved to allow rocking of one block upon another. The structure is held together by tensioned bands and the graphite structure is mounted on ball bearings to allow for thermal expansion. The graphite blocks are formed so that the minimum growth occurs along the longitudinal axes and the side faces are recessed so that contact between adjacent blocks is limited to small bands at the ends. To reduce neutron streaming along the block faces, the crosssection of each block is displaced about the vertical and the gaps between the blocks are thereby interrupted by the block edges.

[Class 40 (iv).] Networks, such as those designed to effect phase compensation or attenuation equalization, comprising reactance elements are corrected for distortion due to inherent resistance or leakance by the addition of suitable resistances. In networks made up in known manner of inverse elements Z1, Z2 (that is, Z1, Z2 = K<2>, a constant), if an inductance coil L in Z1 has inherent resistance r, a resistance K<2>/r is placed in shunt across the corresponding capacity C = L K<2> in Z2, while if a condenser C<1> has leakance equivalent to a shunt resistance r<1>, a resistance K<2>/r<1> is placed in series with the corresponding inductance L<1>= K<2>C<1>. The power factors of corresponding elements are thereby equalized. In practice the resistance K<2>/r<1> is very small and would generally be already present in the inductance coil, making it necessary to consider only the excess of the coil resistance. The coil resistance, which is partly due to losses in the magnetic material, is measured at a suitable mean frequency in the working range. The application to networks of the lattice and bridged T types is described, including those employing mutual inductance.
